Hi Bob,
On Diagram z-32 you show a diode between the coil wires on the S704
relay. On Z-13/8 the S704 that is used in the alternate alternator
circuit has an OVM-14 but no diiode. Will you explain why there is no
diode present in one circuit and there is one present in the other? Does
the OVM-14 negate the need for the diode? Thanks. Don

Good question. There's no reason not to treat
the relay installation you've cited like all the
rest. I'm not real sure how the crowbar module
contributes to the negative spike mitigation . . .
I'll have to go measure that. However, if you'd
like to include a diode on the relay, here's a way
to get it installed.
